自适应数字频率计教学课题的设计

The Design of Adaptive Digital Frequency Meter

本文介绍基于FPGA的自适应数字频率计教学课题的设计。该频率计不仅有基本频率范围测量,还设计了超范围频率测量方法。该课题能综合数字逻辑电路知识,作为可编程器件开发的教学实验课题有非常实用性,能够提高数字逻辑电路和可编程器件应用的教学实验水平。

The design of adaptive FPGA based digital frequency meter for teaching project is presented in the paper.The meter can measure frequency in general range.The way to measure out-of-range frequency is also discussed.There is plenty of comprehensive digital logic circuit knowledge involved in the project.It can be used as teaching material to develop digital logic circuit and programmable logic device due to its practical and interest nature.It will bring the teaching and experiment of digit logic circuit and application of programmable logic device to a new level.
